Specification of Letters Patent. Application filed Decorate/r26, 1905.Serial No. 298.230.

Patented Dec. 25, 1906.

To all (Ii/L077), it may concern:

Be it known that 1, JOHN P. KELLY, a citizen of the United States, anda-resident of Worcester, in the county of Worcester, Com monwealth ofMassachusetts, have'invented new and useful Improvements inWater-Meters, of which the following is a specification.

My. invention relates to improvements in water-meters. Its object is toprovide a water-meter in which the operating-gears and their connectionsare housed outside of the water-containing portion of the meter andeffectually protected from contact with the water. lts object is,further, to provide a disk-chamber which can be perfectly drained.

It also relates'to improved means for mounting the disk-chamber in theinclosing case, obviating the necessity for screw or bolt adjustments.

It also relates to means for adapting my improved meter for use inconnection with upright as well as horizontal service-pipes. In thedrawings herewith accompanying and making a part 'of this application,Figure 1.is a vertical central sectional view of my improvedwater-meter. Fig. 2 is a top plan view of the base or lower portion ofthe diskchamber-inclosing case. Fig. 3 is aplan view of-the top portionof the disk-chamberinclosing case. Fig. 4 is a side elevation of theremovable top of the disk-chamber, it being understood that theremovable bottomof the disk-chamber is the counterpart of the top shownin Fig. 4. Fig. 5 is a side. elevation of the disk-chamber, showing theinlet and outletports. Fig. 6 is a top plan of the'gear-stand upon whichthe registering-gear is mounted. Fig. 7 is a side view of the diaphragmin the disk-chamber, which is vertically positioned between the inletand outlet ports. Fig. 8 is a side elevation of the base or lowerportion of the casing when adapted for use in connection with verticalservice-pipes. Fig.9 is a. plan view looking into the same, and Fig. 10isa front end elevation with the union beingremoved.

The same characters of reference refer to like parts.

In eaid drawings,yA represents the base,

and B the top, of the disk-chamber-inclosing case. The. base-is providedwith an inlet port G andan outlet-port D, each having the usual threadsfor connection with the piping. Formed integral with the, inside of thebase are. disk=chamberlpositionin walls E and F, respectively, the

ple, by nuts and bolts ace of sai walls being in the arc of a circle inhorizontal section and machined. 'lhe disk-chamber has correspondingcircular faces G and H, re- I spectively, and of a radius also machinedto register with a close fit with the parts'E and F aforesaid, wherebythe disk-chamber when in position is held centrally position ed.Centrally positioned in the bottom of the base is 1 a raised ring I. Thedisk-chamber has avertical body J, a-removable top-K, and a removablebottom L, said top and bottom being provided with flanges M, resting onthe edges N of the chamber. I The bottom head of the disk-chamber has abearing-surface O, which rests on the ring I in the bottom of the base,and the contacting faces being carefully machined make a water-tight'oint. Resting between the positioning-walls and F and upon the ring I ythe disk-chamber itself, as well as its component parts,'is held inplace without the use of screws. The top B has downwardly-extendingposts P, which bear directlyupon the top of the disk-chamber, as seen inFig. 1, the top and bottom of the disk-chamber, as well asthedisk-chamber itself, being held rigidly in place without thenecessity of screws or otherv attaching means. The cover itself is heldin place upon the base nthe usual manner-as, for exam- Q on the base andlugs on the top, as seen in Figs. 2 and3. The wall E is spaced apartfrom the case and is open at the top and one side, as shown in Fig. 2,and the wall F has a ppssing through lugs port F therein, as shown in Fi1 and in dot ted lines in Fig. 2.' The disk-c amber has an inlet-port Sand an outlet-port T, the latter being coincident with the outlet-port Fin the base.-

Other than .as herein described the disk- .chamber may be of the usualconstruction, having the ball-diskU mounted therein and a diaphragm Vvertically positioned between the inlet and outlet ports. Thediaphragm.-

has substantially the form shown in Fig. 7,

.the top and bottom ed es W being slightly curved and adapted to p tinto corresponding recesses W in the inner faces of the top and The bodybottom of the disk chamber. part has two or more projections X, both atthe top and bottom, to enter recesses in the to and bottom heads toposition these parts relative to the body, so that the recesses for thedia hragm will always register truly, and

to faci itate the assembling of the parts.v

Above the cover of the disk-chamber is a gear-stand X, upon which theregistering mechanism is mounted. This stand has substantially the formshown in Fig. 6, having a tongue Y adaptedto fit under lugs Z on thecover, portions of the tongue being removed at predetermined distancesapait, as seen at Y, to allow the insertion. of the tongue under thelugs. A slight turning of the stand brings the tongue under said lugsand looks it in place. The top B has a cylindrical bearing 1, in whichis inserted a non-metallic self-lubricat ing bushing 2, such asleatheroid, through which extends a shaft 3, operable by the stem 4 onthe disk in the usual way. The upper end is provided with pinion 5,having gear connection with the registering mechanism, which may be ofthe usual construction. A packing 6, composed of a series of films ofcork, is placed below the non-1n etallic bushing 2 and is compressibleby means of a nut 7- on the bearing 1. The acking is placed at thebottom to thorough y protect the bush ing from the water, thusprotecting the lubricating qualities of the bushing.

In Figs. 8, 9, and 10 is illustrated the means of applying myimprovements to a meter for use in connection with vertical pipes. Thebase A is provided with a lateral projection A, having an inlet-port 8and outlet-port 9, the outlet-port being the higher. The base isprovided with the raised ring I and the centering-walls E and F, asbefore. The outlet-port 9 terminates in the centering-face F and theinlet-port to one side thereof. The disk-chamber is of the sameconstruct-ion as before described, its outlet-port registering with theoutlet-port 9 in the casing. Unions 10 and 11 are adapted to connectwith the service-pipe. Constructed in this way the device is verysimple, can be drained perfectly, and the disk-chamber can be of thesame construct-ion as when used in 'connection with horizontal pipes.

The operation of my improved device is as followsfWater enters throughthe inlet-port into the casing, thence passes into the diskchamberthrough the inlet-port therein and discharges through the outlet-portsin the disk-chamber and base to the service-pipe.

The advantages of my improved watermeter are that its parts are readilyand quickly assembled, the disk-chamber is removably held in placewithout the aid of attaching-screws, either in the assembling of Ithe'parts of the disk-chamber itself or in its relation to thedisk-chamber case, it admits of perfect drainage of the parts whendesired, thus avoiding all liability of water remaining in the meter andinjuring it by freezing, the gearing is entirely separated from thewater-chambers of the meter, and the self-lubricating bushing iseil'ectually protected from the injurious eil'ects of contact withwater.

Having thus described my invention and its use, I claim 1. In a diskwater-meter, the combination with an outer casing comprising a top andbase, the base having inwardly-projeeting centering-faces extendingupwardly from the bottom, one of said centering-faces having anoutlet-port therein, of a disk-chamber having correspondinglaterally-projecting centering-faces extending upwardly from the bottom,one of said faces on the disk-chamber being provided with an outlet-pertnear the bottom to register with said port in the casing thus forming acontinuous waterway directly from the interior of the disk-chamber tothe distributing-pipe.

2. In a disk water-meter, the combination with an outer casingcomprising a top and base, the base having vertically-positioned centering-faces therein spaced apart from the interior wall thereof and asupporting-ring extending upwardly from the bottom thereof and s acedapart from said wall, of a diskcham er having correspondingcentcringfaces on. the outside and a circular rim on the bottom thereofadapt ed to rest down on said ring and means for holding thedisk-chamber against vertical movement.

3. In a disk water-meter, the combination with an outer casingcomprising a top and base, the base being provided with outlet and inletports and centering-faces, of a (llSlichamber mounted in said base andprovided with corresponding centering-faces, the top of the casing beingprovided with projecting posts adapted to rest on the top of thediskchamber, whereby the disk-chamber is held against lateral orvertical movement in the disk-casing.

' In testimony whereof I have signed my name to this specification, inpresence of two subscribing witnesses, this 18th day of December, 1905.
